What is the difference between the dynamic type and the object type in Dart?

• dynamic indicates that the variable's type can change at runtime. Type checks for it are disabled at compile time. This can lead to runtime errors.
• Object is the base class for all objects in Dart. A variable of type Object can hold any value, but to access its properties and methods, explicit type casting or type checking (is) is required. Type checks are performed at compile time.

Example:

// Dynamic - no type check at compile time
dynamic myDynamicVariable = 10;
myDynamicVariable = "hello"; // Allowed

// Object - requires type checks or casting
Object myObjectVariable = 10;
// print(myObjectVariable.length); // Compile error without casting

if (myObjectVariable is int) {
  // Safe to use as int
  int value = myObjectVariable;
  print(value + 5);
}

Key differences summarized in the table:

Feature	dynamic	Object
Type check	Disabled at compile time	Performed at compile time
Safety	Low (risk of runtime errors)	High (with explicit casting)
Member access	Without casting (runtime risk)	Requires explicit casting or checking
Usage	When absolutely necessary, when type is only known at runtime	Storing values of any type, with explicit control when needed
